Imagine a golf ball. That's easy right? Now you probably could lift that golf ball many times without straining. Now imagine that golf ball weighing more than a skyscraper. That's not so easy, because such a thing is not possible here on earth. Out in space, however, this is possible. They are called back holes.
Welcome to the Black Holes class! During the next four weeks, you will be learning about what black holes are, how they are formed, why they exist, etc. At the end of each week, you will be asked to complete a small activity, like answering a few questions based on the lesson. When you finish the whole class, you will be asked to create a final product that displays the knowledge you have gained from this class.
To start you off, let's see if you have any previous knowledge of black holes. Please answer these true or false questions to the best of your ability:
Each large galaxy (i.e. The Milky Way) has a black hole in it's center.
The sun will one day become a black hole, causing another Ice Age.
You can see black holes in the sky if you are in complete darkness.
Black holes obey the laws of gravity.
Black holes are capable of sucking up the whole universe.
The answers to these statements are located at the bottom of this page, under these photos. Don't peek!
These five pictures are all of black holes, but yet they all look different.Why do you think this is?
Well, for one, these pictures of black holes are animated, so of course they look all different! But because of the different gravitational laws of the black holes, it is impossible to completely know what a black hole looks like. The looks of black holes can also depend on how they were formed. You will learn about this later in your lessons.
Here are the answers to the true or false questions from earlier:
